@leocg OK. I can tell that I am not the only one that hates the fact that Opera now opens a lot of my pages in enormous type, adds emoji's I don't understand, never wanted nor did I ask for, etc. with this latest update. Makes me never want to update Opera again, or even to continue using it (it used to be my "Go To" Use it all the time browser until this latest update. Isn't there some way to give me simple instructions on how to fix these problems, not just tell me where to go to fix them. I cannot be the only one who uses Opera who hates these changes and is too stupid to figure out the instructions, I am clueless about "Stack Overflow", etc. to follow some of them. Just first tell me where the Tools stuff is and how to fix the giant fonts, hopefully without doing each one individually, when I get there, and how to do it on the keyboard, not just that it can be done on the keyboard? Really, I didn't (intentionally) cause this new problem, just like I didn't ask for emojis, half the time I don't know what they mean and I probably could just offend someone. Really, Opera used to be a great browser, and maybe will be one once again, when it learns to ask about major changes like this & not dump them on long-time users who don't want them anyway.
Again, if using caps for emphasis is the wrong thing to do, but nothing else seemed to work so I thought I might try it!

@sgunhouse Thank you, but I am just as baffled as before. Could you please just help out an old country doctor that doesn't understand much of this other than I updated Opera and now I can't use the individual windows because the font is too big.
Yes, I know that it can be changed in the menu or with the keyboard except I don't know how to do it on either the menu or the keyboard. Could you please just tell me, step by step (with thing are actually where they seem they should be) how to change that oversized page text front in the menu and on the keyboard, as well as how to disable those emoji's.
Sorry for shouting, but but I need to some step by step directions rather than being told where it can be done. It is just frustrating when I have no idea what to do when I get there.

All of a sudden, last update, every window opens in huge (~50 pitch) letters each of which virtually covers an entire screen page>. When I move the cursor up to the address block, I see approx. four (4) emojis, the meaning of which I know nothing about, so I cannot click on something that I know nothing about.
The word "breadcrumbs" appears on the screen on the left side (next to the sidebar), and I have no idea what that means anyway, so I don't know if it has anything to do with the problem, hence I am including it anyway.
How can I get rid of these giant, meaningless (to me letters, words, etc. and get back to a simple screen. Nothing in all of those steps has done anything but create extra work for me and I really don't have hours to wonder around computer stuff I know nothing about, I just want to get rid of giant useless letters that are rendering Opera totally useless for me. I will up front admit that I am simply a user of computers, and even then reluctantly, but I have no ideas why these changes have occurred, nor how to rid myself of the problem so that I can go back to using Opera as my primary site.

I must be the dumbest Opera User on Earth, but I cannot find a simple explanation as to How I can Assign a Tab to a Workspace? I understand how to establish a workspace, but all of mine are empty because I cannot figure out how to assign any specific tab to any workspace. Can anyone just post a Step by Step Example of How I can Assign an Existing Tab to an Existing Webspace

I have used Opera regularly, however, today when I attempted to open the browser a security box opened and it I am not sure of the exact language but it question something about wanting to change access to the Opera Browser, however I closed out of it because I did not want to change it at all. Now, however, I cannot access the Opera Browser because I am not an authorized user. I own the computer, I should be able to be the administrator without all of this garbage about not being authorized to do things, in this case to open Opera. I don't want to Uninstall Opera, I just want my authority to access the Opera Browser restored.
How can I once again become an authorized user for the Opera Browser, since I do own the computer and am the administrator for all intents and purposes?
As an aside, why does this computer keep on telling me that I don't have the authority to look at things on my own computer? [What is the need for all of this super spy security that denies me access to any of my computer files, as I own all of them?]
